The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050.0 mbar (105.00 kPa, 30.01 inHg), with record highs close to 1085.0 mbar (108.50 kPa, 32.04 inHg).
The reason for this is that Mercury has a thin atmosphere that cannot trap solar heat. Its maximum atmospheric pressure is estimated to be 0.00000000003 pounds per square inch; on Earth, the atmospheric pressure is around 14.7 pounds per square inch.Mercuryâs atmosphere is composed of very small amounts of hydrogen, oxygen, helium and sodium.The planet still get hot on the side that faces the Sun, it experiences the most extreme temperatures, which can reach as high as 700Â° Kelvin (427Â°C).ts maximum atmospheric pressure is estimated to be 0.00000000003 pounds per square inch; on Earth, the atmospheric pressure is around 14.7 pounds per square inch.
